Recurrent unilateral hydrosalpinx: a rare complication of acute perforated appendicitis

Appendectomy and women’s reproductive outcomes: a review of the literature

Background

The most frequent abdominal surgery performed for benign disease in females of fertile age is appendectomy, which remains among the most common surgeries and is a possible cause of peritoneal adhesions. The fact that appendectomy can cause adhesions may lead one to think that this may be a relevant risk factor for infertility; however, there is no universal agreement regarding the association between appendectomy and fertility. The aim of this review is to evaluate weather appendectomy may have a relevant impact on female fertility.

Methods

The search was conducted in PubMed and there was no limitation set on the date of publication. All studies regarding populations of female patients who had undergone appendectomy for inflamed appendix, perforated appendix, or negative appendix between childhood and the end of the reproductive period were included.

Results

Some authors believe that pelvic surgery can cause adhesions which can potentially lead to tubal infertility by causing tubal obstruction or by altering motility of fimbriae, tubal fluid secretion, and embryo transport. On the other hand, the most recent evidence reported that removal of the appendix seems to be associated with an increased pregnancy rate in large population studies.

Conclusion

Despite the existence of contrasting opinions concerning fertility after appendectomy, the most recent evidence suggests that appendectomy may actually lead to improved fertility and decreased time to pregnancy. Appendectomy seems to be correlated with improved fertility and higher pregnancy rates.

Recurrent Bilateral Salpingitis in a Sexually Inactive Adolescent: Don't Forget about the Appendix

BACKGROUND

Salpingitis is an acute inflammation of the fallopian tubes and is extremely uncommon in patients who are sexually inactive or premenarchal.

CASE

We describe a 15-year-old sexually inactive patient with recurrent bilateral salpingitis. After the second episode, she underwent an exploratory laparoscopy and was diagnosed with chronic appendicitis.

SUMMARY AND CONCLUSION

Appendicular involvement should be kept in mind in recurrent salpingitis episodes, especially if previous imaging studies do not show signs of appendicitis. Imaging studies should be repeated in experienced centers in case of recurrent episodes. Laparoscopy is the gold standard for the diagnosis of salpingitis and can confirm appendicular or other abdominal involvement. Early diagnosis can help to prevent recurrent episodes of salpingitis and thus reduce the risk of sequelae.

Development of Pelvic Inflammatory Disease after Ectopic Removal

Although ectopic pregnancy and pelvic inflammatory disease (PID) are separately commonly seen in practice, development of PID after surgical removal is rare. Here, we present the case of a 41-year-old female who was admitted for pelvic inflammatory disease diagnosed after laparoscopic salpingectomy for a ruptured ectopic pregnancy. Treatment required drainage of TOAs with interventional radiology and antibiotic treatment. This case report demonstrates how treatment of PID following ectopic pregnancy is complex and may require surgical- or radiology-guided drainage of infection in addition to common antibiotic treatment. Follow-up and duration of treatment are highlighted.

Tunable Resistive Switching Enabled by Malleable Redox Reaction in the Nano-Vacuum Gap

Neuromorphic computing has emerged as a highly promising alternative to conventional computing. The key to constructing a large-scale neural network in hardware for neuromorphic computing is to develop artificial neurons with leaky integrate-and-fire behavior and artificial synapses with synaptic plasticity using nanodevices. So far, these two basic computing elements have been built in separate devices using different materials and technologies, which poses a significant challenge to system design and manufacturing. In this work, we designed a resistive device embedded with an innovative nano-vacuum gap between a bottom electrode and a mixed-ionic-electronic-conductor (MIEC) layer. Through redox reaction on the MIEC surface, metallic filaments dynamically grew within the nano-vacuum gap. The nano-vacuum gap provided an additional control factor for controlling the evolution dynamics of metallic filaments by tuning the electron tunneling efficiency, in analogy to a pseudo-three-terminal device, resulting in tunable switching behavior in various forms from volatile to nonvolatile switching in a single device. Our device demonstrated cross-functions, in particular, tunable neuronal firing and synaptic plasticity on demand, providing seamless integration for building large-scale artificial neural networks for neuromorphic computing.

Recurrent Pelvic Infections and Salpingitis after Perforated Appendicitis

BACKGROUND

The effect of perforated appendicitis on the adnexa is an issue of concern and controversy. Long-term fertility studies have been conflicting.

CASE

We present the case of a patient with chronic pelvic infections, salpingitis, and hydrosalpinx after perforated appendicitis.

SUMMARY AND CONCLUSION

Magnetic resonance imaging was helpful in diagnosing a chronically obstructed fallopian tube, likely secondary to the dense adhesions from her previously treated perforated appendicitis. Salpingectomy relieved her symptoms of chronic pain and recurrent infections.

Hydrosalpinx in Postmenarchal Nonsexually Active Girls: A Review of 6 Cases in a Children's Hospital

BACKGROUND

The objective of the study was to identify the presence of hydrosalpinx in postmenarchal nonsexually active girls in a children's hospital and to review the available literature on hydrosalpinx in this population.

CASES

In a tertiary care children's hospital, we performed a retrospective review of charts from January 1, 2000 to December 31, 2014 and identified six cases of hydrosalpinx in postmenarchal nonsexually active female adolescents ranging in age from 12 to 19 years old. The diagnosis of hydrosalpinx was made using imaging studies. Four of six patients were symptomatic at presentation, and two patients were diagnosed when seen for unrelated reasons. Five of these six girls had previous abdominopelvic surgery. Four girls were given empiric antibiotic treatment for presumed pelvic inflammatory disease related to hydrosalpinx. Two patients required surgical intervention that resulted in complete resolution of the hydrosalpinx. The oldest patient in the series underwent ultrasound-guided drainage of the pyo- and/or hydrosalpinx with subsequent recurrence with tubal ovarian abscess five months later.

SUMMARY AND CONCLUSIONS

The presence of hydrosalpinx might be discovered in the workup of pelvic pain in nonsexually active adolescents or on routine follow-up in patients with previous abdominal surgery, some of whom are asymptomatic. The underlying pathophysiology for hydrosalpinx in this population remains unclear. Among our cases, postsurgical adhesions appeared to be the most likely predisposing factor for tubular obstruction. Early detection and prompt diagnosis will allow for appropriate conservative or definitive treatment.

Best practice in management of paediatric and adolescent hydrosalpinges: a systematic review

BACKGROUND

Hydrosalpinx is a rare cause of abdominal pain in paediatric patients, though cases are documented in the literature. Its aetiology differs considerably from traditional hydrosalpinx due to ascending sexually transmitted infection. Hydrosalpinx can present mimicking an acute abdomen or can be asymptomatic. Management of paediatric hydrosalpinx varies, but often involves surgical removal of the affected tube.

METHODS

In June 2015, a literature search using relevant keywords was completed on MEDLINE and EMBASE databases to determine best management of paediatric hydrosalpinx.

RESULTS

We found 66 cases from 38 articles. Surgical intervention took place in 74% of cases (n=49). The most common surgical intervention was salpingectomy. In 3% of cases (n=2), nonsurgical medical management with hormonal therapy was utilized, with post-operative improvement in symptomology. In 23% of cases (n=15), conservative management was utilized: 2 of these cases torted, 4 cases persisted and 9 cases resolved.

CONCLUSION

Overall, the results of this review demonstrate that there are comparable outcomes between surgical, medical and conservative management. However, medical and conservative management was not often offered, and more research is needed on the subject.
